DUST-GUARD FOR WINDOWS.

SPECIFICATION forming part of Letters Patent No. 739,115, dated September 15, 1903.

Application filed March 18, 1903 To 01. whom it may concern.-

Be it known that LFRANK R. SIMMS, a citizen of the United States, residing at Columbus, in the county of Lowndes and State of Mississippi, have invented a new and useful Dust- Guard for Windows, of which the following is a specification.

This invention relates to devices employed for preventing dust,cinders, and other similar floating matter from entering open windows, more particularly of railway-coach windows; and the object of the invention is to simplify and improve devices of this character and increase their efficiency and portability without Fig. 2 is a perspective view' enlarged of the" device detached and partially folded.' Fig. 3 is a perspective view enlarged of the device folded for transportation or storage.

The improved device consists in a supporting-bar formed in two or more sections, as at 10 11, connected by a hinge 12 at their adjacent ends, and thus rendered foldable when not in use, and provided with a catch means for supporting the sections in their extended position, the catch member consisting of a bar 13, pivotally connected at one end at 14 to one of the sections 10 and with the other end provided with a recess 15, adapted to engage a pin 16 on the other section 11, as shown in Fig. 2. The catch member 13 will preferably operate in recesses formed in the bar sections 10 11, as indicated, so that no portion of the catch member projects beyond the body portions of the foldable bar.

Attached respectively to the bar-sections 10 11, preferably on 'the'hinge side and extending therefrom, are wing members 17 18 with their adjacent edges overlapping, as indicated at 19, to more effectually resist the air-currents and prevent the passage of dust particles between the sections. This is an important feature of the invention and adds materially to the value and efficiency of the Serial No. 148.421. (No modeLl invention, as allgaps between the wing-sections are obviated without increasing the weight or expense.

The bar-sections 10 11 will preferably be of wood, and the wing-sections may be of light wood,'n1etal, or some form of composition, such as paper of requisite strength and tenacity, and will be of any desired area.

Attached respectively to the bar-sections 1O 11 are spring guard-plates 2O 21, adapted to swing over the surface of the wings opposite to the direction in which the cars are moving and provide supports thereto to prevent the force of the wind from collapsing the wings. These guard-strips are an important feature of the invention and enable a lighter material to be employed for the wings than would be possible without them, while at the same time they can be formed of such light material that they do not materially increase the weight.

The foldable bar 10 11 will be adapted to fit into the recess or groove in which the window-sash slides, as shown, with the wingsections extending outwardly at right angles to the window, and will be retained in position by the gravity of the sash, which is lowered down in engagement with the upper end of the bar-sections.

When not in use, the device will be folded together and can then be carried in a valise with other articles and will not add materially to the weight of the baggage carried by the traveler. If preferred, the wings may be curved, and this form may be employed under some circumstances, 'lhe'devices may thus be carried by travelers in their journeys and. employed when required or they may be furnished by railroad or carcompa nies or used as a part of the regular equipment of the car. A holding-loop 22 may be attached in any suitable manner to one of the wings or supporting-bars to assist in the adjacent edges of the wings overlapping,

substantially as described.

sections and adapted for extension transversely of said wing-sections substantially as described.

In testimony that I claim the foregoing as I 3 my own I have hereto affixed my signature in the presence of two witnesses.

FRANK R. SIMMS.
